EDGETRANSG(1)

🦋 edgetransg — the girlies' guide to picking out symmetric graphs

okay so hi bestie 💖 you've stumbled into edgetransg, which lives in the User Commands corner of your manual and is literally just the little tool for sorting undirected graphs by how much symmetry they've got going on. version 2.9.3, if we're being specific. she's an icon, she's niche, she knows exactly what she's about. 👑

---

✨ SYNOPSIS ✨

edgetransg [-t] [-q] [infile [outfile]]

like, that's it. that's the whole vibe. you feed her an infile and an outfile (both optional, no pressure), toss in some flags, and she does her thing. 🎀

---

🌸 DESCRIPTION 🌸

so what does she actually do? bestie, she selects undirected graphs according to group action on vertices, edges and arcs. that's the whole job. you hand her graphs, she keeps the ones whose symmetry matches whatever you asked for, and the rest can go home. slay. 💅

⚠️ heads up though: digraphs are not supported yet. directed graphs, she does not do. not today, maybe someday, but not today. 😭

and here's a detail that lowkey matters a lot: the output file has a header if and only if the input file does. so if your input came with a header, congrats, your output gets one too. if it didn't? nope, she's not adding one. it's giving ✨respect for the original format✨. 🦋

now for the flag menu, because this is where the main character energy really kicks in. every single one is a requirement — she filters, she doesn't suggest. 🌈

• -v — require vertex-transitive. if it ain't vertex-transitive, it's not making the cut. periodt.
• -V — require not vertex-transitive. the exact opposite bestie. anti-vertex-transitive. chaotic, love that for her. 💀
• -e — require edge-transitive. edges gotta be symmetric, no exceptions.
• -E — require not edge-transitive. again, the villain edit. she's keeping the messy ones. 🙈
• -a — require arc-transitive. arcs need that symmetry glow-up. ✨
• -A — require not arc-transitive. the flip side, as always. not symmetric, please and thank you. 💅
• -q — suppress auxiliary information. quiet mode! she stops narrating and just does the job. sometimes you just want the results without the commentary, and honestly? relatable. 🤫

💖 tiny note: the synopsis up there also shows a -t flag — the page itself doesn't say anything more about it, so I'm not gonna sit here and make things up about it. iykyk. 🫶

👑 one last thing 👑

so like, that's the whole page, bestie. no environment variables, no exit statuses, no files list, no SEE ALSO — she keeps it short and sweet and honestly? iconic behaviour. ⭐

this little love letter was brought to you by edgetransg 2.9.3, dated September 2026. go forth and filter some graphs. you're gonna eat. 🔥💜
